Hi,

   

            According to RFC 3261 19.1.1

     "The set of valid telephone-subscriber strings is a subset of valid
user strings."

 

     Since the 'user' info part of SIP URL does not cover "#" symbol
according rfc 3261 syntax for 'user'.

According to RFC 2806, the syntax for telephone-subscriber is

telephone-subscriber= 1*dtmf-digit

dtmf-digit            = "*" / "#" / "A" / "B" / "C" / "D"

 

 

How can telephone-subscriber string is a subset of valid user string? 

 

Can you please help to resolve the above statement?

 

Thanks & Regards,

Anil
